OBJECTIVE To investigate the effects of subanesthetic dose of esketamine on postoperative anxiety and recovery in patients undergoing laparoscopic cholecystectomy. METHODS A total of 200 patients scheduled for laparoscopic cholecystectomy at Suzhou Ninth Hospital Affiliated to Soochow University from January 2023 to December 2024 were randomly assigned to control group (n=100) and observation group (n=100). One minute before the initiation of anesthesia, patients in the control group received intravenous injections of Propofol emulsion injection, Sufentanil citrate injection, and Succinylcholine chloride injection. On this basis, patients in the observation group received an intravenous injection of Esketamine hydrochloride injection. The anxiety status of patients in both groups was compared, along with their general intraoperative conditions (including sufentanil dosage, duration of pneumoperitoneum, operative time, anesthesia time, and extubation time), postoperative recovery, incidence of adverse reactions, and the need for dezocine rescue analgesia. Heart rate and mean arterial pressure, entropy index (state entropy and response entropy), inflammatory marker levels [interleukin-6 (IL-6) and C-reactive protein (CRP)], numerical rating scale (NRS) for pain intensity were compared between the two groups at different time points. RESULTS No significant differences were found between the two groups in pneumoperitoneum duration, operative time, anesthesia time,extubation time, incidence of postoperative dry mouth, entropy index or length of stay in the post-anesthesia care unit (P>0.05). Compared with the control group, the observation group showed significantly lower postoperative STAI-S scores, reduced intraoperative sufentanil consumption, decreased incidence of postoperative nausea, vomiting, and shivering, the need for dezocine rescue analgesia, as well as lower plasma IL-6 and CRP levels at 24 h after surgery, and NRS (P<0.05). The heart rate and mean arterial pressure of patients in the observation group at the start of surgery, end of surgery, and during extubation were all significantly higher than those in the control group (P<0.05). CONCLUSIONS Subanesthetic dose of esketamine can effectively alleviate postoperative anxiety, reduce intraoperative opioid consumption, suppress postoperative inflammatory response, relieve postoperative pain, and promote recovery in patients undergoing laparoscopic cholecystectomy.

ObjectiveTo study the pharmacological substances and mechanisms through which sesquiterpene ZH-13 from Aquilariae Lignum Resinatum improves neuroinflammation. MethodsBV-2 microglial cells were stimulated with lipopolysaccharide (LPS) to induce neuroinflammation. The cells were divided into the normal group, the model group, and the ZH-13 low- and high-dose treatment groups (10, 20 μmol·L-1). The model group was treated with 1 μmol·L-1 LPS. Cell viability was assessed using the cell proliferation and activity assay (CCK-8 kit). Nitric oxide (NO) release in the cell supernatant was measured using a nitric oxide kit (Griess method). The mRNA expression levels of interleukin-1β (IL-1β), tumor necrosis factor-α (TNF-α), inducible nitric oxide synthase (iNOS), and interleukin-6 (IL-6) were detected by real-time fluorescence quantitative polymerase chain reaction (Real-time PCR). The phosphorylation of mitogen-activated protein kinase (MAPK) pathway proteins was assessed by Western blot. ResultsCompared with the model group, ZH-13 dose-dependently reduced NO release from BV-2 cells under LPS stimulation (P<0.05, P<0.01). In the 20 μmol·L-1 ZH-13 treatment group, the mRNA expression levels of IL-1β, TNF-α, iNOS, and IL-6 were significantly reduced compared to the model group (P<0.05, P<0.01). In both the low- and high-dose ZH-13 groups, the expression of the inflammatory factor TNF-α and the phosphorylation of c-Jun N-terminal kinase (JNK) in the upstream MAPK pathway were significantly reduced (P<0.05). After stimulation with the JNK agonist anisomycin (Ani), both low- and high-dose ZH-13 treatment groups showed reduced phosphorylation of JNK proteins compared to the Ani-treated group (P<0.01). ConclusionThe sesquiterpene compound ZH-13 from Aquilariae Lignum Resinatum significantly ameliorates LPS-induced neuroinflammatory responses in BV-2 cells by inhibiting excessive JNK phosphorylation and reducing TNF-α expression. These findings elucidate the pharmacological substances and mechanisms underlying the sedative and calming effects of Aquilariae Lignum Resinatum.

ObjectiveTo investigate the association of menopausal time and menopausal age with the risk of nonalcoholic fatty liver disease (NAFLD), and to provide a basis for the early prevention and treatment of NAFLD in clinical practice. MethodsRelated data were collected from 373 postmenopausal women who attended the outpatient service of Department of Spleen, Stomach, Liver and Gallbladder Diseases, The First Affiliated Hospital of Henan University of Chinese Medicine, from January 2017 to December 2021, including general information, menopausal age, menopausal time, and presence or absence of NAFLD. The chi-square test was used for comparison of categorical data; the independent-samples t test was used for comparison of normally distributed continuous data between groups, and the Wilcoxon rank-sum test was used for comparison of non-normally distributed continuous data between groups. A Logistic regression analysis was used to calculate the association intensity and 95% confidence interval (95%CI) of menopausal time and menopausal age for the risk of NAFLD, and the restricted cubic spline (RCS) method was used to investigate the dose-response relationship between menopausal time/age and the risk of NAFLD. ResultsCompared with the women with normal menopause or late menopause, the women with early menopause had a higher prevalence rate of NAFLD and a higher degree of steatosis and fibrosis (all P<0.05). After adjustment for the confounding factors such as age and age of menarche, the risk of NAFLD in women with a menopausal time of >3 years was 4.80 (95%CI: 1.93 — 11.95, P=0.001) times that in women with a menopausal time of ≤3 years, and the risk of NAFLD in women with early or late menopause was 8.14 times (95%CI: 1.77 — 37.58, P=0.007) and 0.09 times (95%CI: 0.03 — 0.32, P<0.001), respectively, that in those with a normal menopausal age. There is a dose-response relationship between menopausal time/age and the risk of NAFLD. Menopausal time is positively correlated with the association intensity of NAFLD, while menopausal age is negatively correlated with the association intensity of NAFLD. ConclusionThe longer the menopause time and the earlier the menopause age, the ligher the risk of NAFLD.

Chronic liver diseases with common causes including viral infections, alcohol abuse, and autoimmune diseases. Alkaloids, as a class of plant-derived compounds, have shown significant potential in regulating chronic liver diseases. Recent studies have shown that alkaloids are able to exert a therapeutic effect on chronic liver diseases through multiple pathways. These compounds have a regulatory effect on key pathological processes such as liver fibrosis, inflammatory response, oxidative stress, and cell apoptosis, and they also regulate the metabolic homeostasis of hepatocytes by modulating multiple signaling pathways, thereby playing a role in regulating chronic liver diseases. This article reviews the role and mechanism of alkaloids in the treatment of chronic liver diseases, in order to provide new ideas and directions for the treatment of chronic liver diseases.

ObjectiveTo observe the clinical efficacy of modified Jinwei Guben Decoction (金卫固本汤, MJGD) combined with Bailing Capsule (百令胶囊, BC) in the treatment of chronic obstructive pulmonary disease (COPD) patients in the stable stage with qi deficiency, blood stasis and phlegm obstruction syndrome, in addition to conventional western medicine treatment. MethodsA total of 102 patients with stable COPD and qi deficiency, blood stasis, and phlegm obstruction syndrome were included in the study. According to the patients'preferences, they were divided into treatment group (49 cases) and control group (53 cases). The control group received conventional western medicine treatment, while the treatment group was given MJGD (1 dose daily) combined with BC (2.0 g each time, three times a day) additionally. The treatment period was 3 months, and the patients were followed up for 1 year after the treatment. The acute exacerbation frequency (mild, moderate, severe) before treatment, during treatment, at 6-month follow-up, and at 1-year follow-up was compared between groups. Additionally, the lung function indicators such as FEV1, FEV1%pred, FVC, and FEV1/FVC ratio, traditional Chinese medicine (TCM) syndrome scores, modified British Medical Research Council (mMRC) dyspnea scale, and the COPD Assessment Test (CAT) scores before and after treatment were compared. A logistic regression model was constructed to analyze the impact of MJGD combined with BC on clinical efficacy. ResultsFour patients dropped out from the treatment group and eight from the control group, leaving 45 patients of each group for statistical analysis. The number of mild and moderate acute exacerbations in the treatment group was lower than that in the control group during the treatment period, at 6-month follow-up and within 1 year of follow-up (P<0.05) .The number of severe acute exacerbations was only lower in the treatment group than in the control group at 6-month follow-up (P<0.05). Compared with that before treatment, the number of acute exacerbations of all degrees in the treatment group was significantly reduced within 1 year of follow-up (P<0.05),while only the number of mild acute exacerbations in the control group was significantly reduced within 1 year of follow-up (P<0.05). The treatment group showed significant improvement in FEV1 and FEV1%pred and FEV1/FEV, while the control group showed a significant decline in FEV1 and FVC (P<0.05). After treatment, both groups showed significant reductions in TCM syndrome scores, including coughing, sputum, wheezing, chest tightness, shortness of breath, and fatigue, as well as mMRC and CAT scores (P<0.05), with the treatment group having significantly lower scores than the control group (P<0.05). The overall clinical effective rate of in the treatment group was 93.33% (42/45), significantly higher than that of the control group, 75.56% (34/45, P<0.05). Multivariate logistic regression analysis showed that the use of MJGD combined with BC (OR = 4.68, 95%CI: 1.15 - 19.09, P = 0.03) was positively correlated with clinical efficacy. ConclusionsIn addition to conventional western medicine treatment, the combination of MJGD and BC can reduce the frequency of acute exacerbations, delay the decline of lung function, improve clinical symptoms, and significantly enhance the clinical efficacy in patients with stable COPD and qi deficiency, blood stasis, and phlegm obstruction syndrome.

AIM: To evaluate the repeatability and accuracy of iCare IC100 tonometer in measuring intraocular pressure(IOP)by comparing the correlation and difference with Goldmann applanation tonometry(GAT)and non-contact tonometer(NCT), and to compare the correlation of the three types of IOP measurement with the central corneal thickness(CCT).METHODS: Prospective study. A total of 90 outpatients(90 eyes)in Liaoning Aier Eye Hospital from March 2019 to May 2019 were randomly selected as study subjects. All patients were measured IOP using iCare IC100, NCT, and GAT. The interclass correlation coefficient(ICC)was used to evaluate the repeatability of IOP measured 3 times consecutively using an intraocular tonometer. The correlation and consistency of iCare IC100, GAT and NCT were compared by one-way ANOVA, Pearson linear correlation analysis and Bland-Altman analysis. The linear regression analysis was used to analyze the correlation of the three tonometers with CCT.RESULTS: The mean IOP measured with iCare IC100, GAT and NCT was 19.74±6.90, 19.88±7.07 and 18.47±6.31 mmHg, respectively(F=1.180, P=0.309). The measurements of iCare IC100 with GAT, iCare IC100 with NCT and GAT with NCT were all positively correlated(r=0.930, 0.946, 0.918, all P<0.05), the Bland-Altman analysis showed that the mean differences between iCare IC100 and GAT, iCare IC100 and NCT, GAT and NCT were -0.142±2.61, 1.27±2.24, and 1.41±2.81 mmHg, respectively, with 97%(87/90), 96%(86/90), and 97%(87/90)IOP differences distributed within their 95% confidence intervals. The IOP measured with iCare IC100 and CCT, GAT and CCT and NCT and CCT were all positively correlated(r=0.426, 0.353, 0.451, all P<0.01). The linear regression equations between iCare IC100, GAT and NCT measurement and CCT were iCare IC100 IOP=-19.62+0.074×CCT; GAT IOP=-13.54+0.063×CCT; NCT IOP=-19.65+0.072×CCT; that is, for every 10 μm increase in CCT, iCare IC100 measurement increased by 0.74 mmHg, GAT measurement increased by 0.63 mmHg, and NCT measurement increased by 0.72 mmHg.CONCLUSION: The iCare IC100 tonometer has good repeatability and accuracy in measuring IOP, and the CCT has a greater impact on the measurement of iCare IC100 than the GAT and NCT.

AIM: To delineate the specific mutation responsible for retinitis pigmentosa(RP)in a Yi pedigree, and to analyze the correlation of RHO gene mutation with clinical phenotype.METHODS:A comprehensive clinical evaluation was conducted on the proband diagnosed with RP and other familial members, complemented by a thorough ophthalmic examination. Peripheral blood samples were obtained from the proband and familial members, from which genomic DNA was extracte. Subsequent whole exome sequencing(WES)was employed to identify the variant genes in the proband. The identified variant gene was validated through Sanger sequencing, then an in-depth analysis of the mutation genes was carried out using genetic databases to ascertain the pathogenic mutation sites. Furthermore, an exhaustive analysis was performed to delineate the genotype and phenotype characteristics.RESULTS:The RP pedigree encompasses 5 generations with 42 members, including 19 males and 23 females. A total of 13 cases of RP were identified, consisting of 4 males and 9 females, which conforms to the autosomal dominant inheritance pattern. The clinical features of this family include an early onset age, rapid progression, and a more severe condition. The patients were found to have night blindness around 6 years old, representing the earliest reported case of night blindness in RP families. The retina was manifested by progressive osteocytoid pigmentation of the fundus, a reduced visual field, and significantly decreased or even vanished a and b amplitudes of ERG. The combined results of WES and Sanger sequencing indicated that the proband had a heterozygous missense mutation of the RHO gene c.1040C>T:p.P347L, where the 1 040 base C of cDNA was replaced by T, causing codon 347 to encode leucine instead of proline. Interestingly, this mutation has not been reported in the Chinese population.CONCLUSION:This study confirmed that the mutant gene of RP in a Yi nationality pedigree was RHO(c.1040C>T). This variant leads to the change of codon 347 from encoding proline to encoding leucine, resulting in a severe clinical phenotype among family members. This study provides a certain molecular, clinical, and genetic basis for genetic counseling and gene diagnosis of RHO.
